What's this?The overall score for a tested model is based on CR's results from more than 50 tests and evaluations. You can easily see how its overall score compares with the "Highest" and "Lowest" rated vehicles in its category. The overall score was revised in spring 2014 to better reflect the state of the art for today's cars and how drivers use them.

Nimble and capable handling, a taut ride, and excellent braking make the ATS a treat to drive. Three engines are available, with rear- or all-wheel drive: a 2.5-liter four-cylinder, a 3.6-liter V6, and a 2.0-liter turbo four-cylinder. The turbo feels quicker than it is but got just 23-mpg overall. The six-speed automatic is a step behind the seven- and eight-speeds in most competitors. A manual gearbox is available. The interior is well-finished but very snug. Interacting with the audio or phone through Cadillac's Cue system, with its flush buttons and dazzling display, is very convoluted and frustrating. A coupe is available, and a high-performance ATS-V with a 445-hp, twin-turbo 3.6-liter V6 arrives this spring.
